Very nice video, ty! I have a setup with 19c RAC (2 nodes), 1cdb, 1 pdb. When I start the virtual machines I check crsctl stat (2 X Instance Shutdown,STABLE), next step is -- srvctl start database -d database_name, after this step, cdb is in open mode and the pdb is in mount mode. I expected that pdb to be in open mode also. Is it any srvctl command to open pdb (both instances)? Now I open pdb using "alter pluggable database pdb_name start instances=ALL;

[@Mallik034]

by default your PDBs will goes to mount mode, You have to set defaut option as open mode for you PDBs so that the moment you open you CDB all your PDBs also get open.

very nice
